Earthquakes matter little: NRCan’s model puts building losses at $0.004 a year per $1,000 of value, against $0.030 for the typical town. Fewer homes than usual carry radon here, 0% over the guideline where the typical town has 6.6%. Cape Dorset can’t get a Hazard risk grade: it lies north of the fuel map, so its wildfire risk can’t be measured. Cape Dorset grades A+ for hazard risk, without a wildfire figure.
What stands out about Cape Dorset’s hazards
For Cape Dorset, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Cape Dorset faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Cape Dorset grades A+ for hazard risk
Earthquake risk and radon make Cape Dorset’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 78 home tests in the survey area, so a few homes move it.
No wildfire figure for Cape Dorset
Cape Dorset lies north of the national fuel map, so its wildfire risk isn’t measured, and Risk can’t be graded without it.
No flood study is listed for Cape Dorset
Flood studies whose area touches Cape Dorset, from NRCan’s inventory, each linked to its owner.
No flood study on the national inventory covers Cape Dorset; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
No inventory study touches Cape Dorset, where 58% of Canadian towns have one.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Cape Dorset.
The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”
Little shaking expected in Cape Dorset: $0.004 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Shaking costs the typical town $0.030 a year; in Cape Dorset it is only $0.004, 0.1 times as much.
Shaking damage a year per $1,000 of building value
Canada’s median, $0.030, is the yardstick for Cape Dorset ($0.004): there are too few towns in Nunavut for one of their own.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Nearly every one of Canada’s 2,611 towns (98%) expects more shaking damage than Cape Dorset.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
For Cape Dorset the model prices shaking damage to buildings, nothing more.

Little radon around Cape Dorset: 0% of area homes over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
Cape Dorset’s area, at 0%, is below the 6.6% of the typical Canadian town, though any one home can still be high.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
There is no median in Nunavut to compare with: the territory has too few towns, so Cape Dorset’s 0% stands beside Canada’s figure.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
63% of Canada’s 2,611 towns have a higher share of homes over 200 Bq/m³ than Cape Dorset’s band, which holds 37%.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
Health Canada advises testing every home, Cape Dorset’s included, whatever the area’s figure.

Where to get warnings in Cape Dorset
Environment and Climate Change Canada issues the weather alerts for Cape Dorset; Alert Ready carries the urgent ones to phones, radio and TV.
| Alert | What it means |
|---|---|
| Warning | Severe weather is happening or about to: act now. |
| Watch | Conditions favour severe weather: be ready. |
| Advisory | Weather that is less severe but could disrupt the day. |
| Special weather statement | Unusual weather worth knowing about. |
| Special air quality statement | Poor air, often wildfire smoke. |
In fire season, check CWFIS for danger and active fires around Cape Dorset, and listen to local authorities for orders.

Get ready for what Cape Dorset faces
Practical steps for Cape Dorset’s hazards, most pressing first.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Cape Dorset takes its 2007 health region’s share.
- Wildfire counts one way. For Cape Dorset, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Cape Dorset.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Cape Dorset’s census subdivision (a neighbourhood shows its city’s).
Questions about flooding and hazards in Cape Dorset
Is radon a problem in Cape Dorset?
The area’s survey found 0% of 78 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Cape Dorset.
Does Cape Dorset flood?
The inventory has 0 studies for Cape Dorset, and an empty list isn’t a clean bill: the municipality holds any flood maps.
How is Cape Dorset’s Hazard risk Grade worked out?
Hazard risk gives Cape Dorset A+, weighing earthquakes and radon and counting wildfire only against it.
How big is the earthquake risk in Cape Dorset?
About $0.004 a year per $1,000 of building value, NRCan’s long-run expectation for Cape Dorset.
